2050 class

In late 2011, TasRail purchased four 2150 class from QR National. All four locos were railed south to Brisbane, then road freighted in pairs to Tasmania and finally railed from Devonport to Launceston workshops for modifications prior to entering service. The locomotives purchased were 2150, 2151, 2153 and 2154 and until withdrawal (some only shortly before shipping) they were in use on Nickel ore train in the Townsville region. The first two arrived in Tasmania on 6 November 2011, the remaining pair following a fortnight later.

The QR 2100 series comprised a number of sub types representing evolving technology over the 10 years of deliveries, and also different funding arrangements, and like the ZB class (former QR 2350/2370 classes) were built for central Queensland coal traffic. They were constructed with a number of variations from 1970, with the purchased locomotives dating from late 1978/early 1979. They are broadly similar to the two existing D class locomotives.

The locomotives were renumbered to 2051 to 2054, with 2051 and 2052 being tested in late February 2012 and entering general service in March. The remaining two locomotives entered service in April. The locos were not repainted and entered service in QR livery, although with Tasrail logos on the long hood side replacing the QR logos.

The four locomotives were stored in early/mid 2015 following delivery of the TR class, and despite being the subject of various rumours as to whether they will be reactivated or sold interstate as at early 2016 they remain at East Tamar.
